Okay, I need some assistance

I have several icon images that I would like to combine into a single animated icon, but I haven't the faintest idea how to go about it. Is there a particular program that does this? Will someone do me the favor of pointing me in the right direction?

Frank Sinatra was right

Love and marriage, love and marriage
Go together like a horse and carriage
This I tell you brother
You can't have one without the other

Love and marriage, love and marriage
It's an institute you can't disparage
Ask the local gentry
And they will say it's elementary

Try, try, try to separate them
It's an illusion
Try, try, try, and you will only come
To this conclusion

Love and marriage, love and marriage
Go together like a horse and carriage
Dad was told by mother
You can't have one without the other

( Unless... )
